Take your survey data and code the gender question as Male= 0 and Female = 1. Suppose we hypothesize that women are more likely to respond to surveys than men are. Specifically, we believe that more than 55 percent of all respondents are women which equates to the proportion of the gender variable to be greater than 0.55. Test the hypothesis. Females= 24 Males= 9 Provide the 6 step process of testing the hypothesis. Present your results and discuss why...

7) First-born children tend to develop language skills faster than their younger siblings. One possible explanation for this phenomenon is that first-borns have undivided attention from their parents. If that explanation is correct, then it is also reasonable that twins should show slower language development that single children and that triplets should be even slower. Davis (1937) investigated this possiblity The following data are similar to what Davis found. The scores represent a measure of language...

Which of the following is not one of the four steps of hypothesis testing: Question 15 options: a) Plot the distribution of the sample means to ensure the data is normal b) Translate the claim into a hypothesis statement c) Organize the data given in the problem and check assumptions d) Use the appropriate test to calculate the test statistic and its corresponding p value e) Reject or fail to reject the null hypothesis, H0

Question 3 (1 point) Hypothesis Test. Gender bias researchers compared the promotion rate of 412 women in manufacturing management positions to the national average which was known to be 75 months for a mostly male population. They measured the number of months each woman worked in middle management before being promoted to senior management, and found an average 79 months (s.d. = 19). Researchers want to know if women are promoted more slowly (i.e. after a larger number of months)....

H0: Gender and type of media is independent H1: Gender and type of media is not independent If for above test, p-value is 0.255 and alpha is 0.05 then which one is correct one? a. Since p-value is larger than 0.05, do not reject H0. Thus, there is evidence that gender and type of media are not independent. Type 1 = 0 and Type 2 = Unknown. b. Since p-value is larger than 0.05, reject H0. Thus, there is no...

take your survey data and code the gender question as Male=0 and Female=1. Suppose we hypothesize that women are more likely to respond to surveys than men are. Specifically, we believe that more than 55 percent of all respondents are women (this equates to the proportion of the gender variable to be greater than 0.55). Use the methods learned this week to test this hypothesis. Males participated in the survey are 24. The number of females are 26. Make sure...

Many survey results have reported a significant gender gap in Canadian public opinion. The federal elections results also show some signs of the gender gap in Canadians' voting preferences. In order to investigate a recent trend, a political party randomly selected 2,500 Canadians. The respondents who were eligible to vote in Federal and Provincial elections in Canada were classified by gender (male or female) and by voting preference among three major political parties (Conservative. NDP or Liberal). The results are...
